An interesting scenario with in general large impact on the renormalization group running of the SM couplings is given by extra-dimensional setups. Although warped models and Gauge-Higgs-Unification setups are more attractive in general, being dual to composite Higgs models via the AdS/CFT correspondence (see e.g. [1]} in the context of unification), we focus on universal (flat) extra dimensions [2]}. Here, the presence of a tower of Kaluza-Klein (KK) excitations effectively turns the running from logarithmic to power law [3]}, [4]}.
